Susceptibility of some Varieties and Breeding lines of Tomato to Liriomyza spp. infestation in Central Sudan

Abstract: 
Tomato crop in the central Sudan is liable to heavy infestation by the leaf miners, Liriomyza spp. Field experiments indicated significant differences in varietal susceptibility of varieties and tomato breeding lines to Liriomyza spp. The breeding line Trop G 9–18 and the varieties, Alfa, Peto 86 and Strain B were the least infested (resistant). Laboratory tests revealed that Flora Dade was more susceptible to L. sativae than Trop-G, whereas the latter was resistant to L. trifolii. Resistance is attributed to anti-feedants and also associated with the glandular trichomes on the leaves.
La culture de tomate dans le centre du Soudan est susceptible de forte infestation par les mineuses des feuilles, Liriomyzaspp. Les expériences sur terrain ont indiqué des différences significatives dans la sensibilité variétale des variétés et des lignées de reproduction des tomates auLiriomyzaspp. La lignéede reproduction Trop G 9-18 et les variétés, Alfa, Peto 86 et la souche B ont été les moins infestées (résistantes). Des tests au laboratoire ont révélé que Flora Dade était plus sensible auL. sativaeque Trop-G, tandis que le dernier était absolument résistant auL. trifolii. La résistance est attribuée aux antinourrisseurs et également associée aux trichomes glandulaires sur les feuilles.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Integrated Crop Management
